Prospective, randomized, pathologist-blinded study of disposable alligator-jaw biopsy forceps for gastric mucosal biopsy
چکیده انگلیسی

BackgroundEndoscopic biopsy forceps differ in the size and shape of the biopsy cup and the presence or absence of a needle.MethodsWe compared four different “large cup” forceps (three with needles) designed for 2.8 mm biopsy channels. A gastric antral and corpus biopsy were obtained with each. Parameters examined included: weight (mg), length (mm), orientation (poor, good), intactness (1, 2, or 3 pieces), depth (superficial, above muscularis mucosae, included muscularis mucosae), crush artefact (yes, no), and overall adequacy (inadequate, suboptimal, adequate).ResultsTwenty-four patients were enrolled (191 biopsies). The median length was approximately 5 mm (range 1.1–8.2 mm). Histologically inadequate specimens were present in 4% with the forceps without needle compared to 16% of those with needles (P = 0.061) and there were significantly fewer specimens in three or more pieces than did the forceps with needles 2.1% vs. 12.6% (P < 0.05).ConclusionsCurrent alligator style forceps provide a high proportion of acceptable specimens with only minor differences between brands. Forceps from one source were least preferred by endoscopy assistants and had the highest rates of inadequate biopsies and biopsies with crush artefact. Forceps without needles provide histologically acceptable samples slightly more frequently than those with needles.
